Thread: 80 series landcruiser transmission cooler

Do you have a temperature gauge on the trans?

I like to have one,my current wagon has one as standard and I installed one on my previous wagon.

If for no other reason than it might remind you to run the trans down to cool off.

Last year I drove over a mountain pass at 2000 meters in about 30 minus with the wind chill. My trans with two coolers plus the circuit in the radiator was reading 20 deg c.

Cruising on the flat in top year towing a loaded trailer at say 20 deg ambient,the trans reads about 40 c.

So there must be alot of warm fluid in the friction parts of the trans despite the three coolers if the difference through a 50 degree spectrum is only 20 deg in the actual transmission.
